An apparatus is disclosed for cutting target material which includes a housing having an inner cavity and an elongated nozzle extending from the inner cavity to communicate with the exterior of the housing. The apparatus is provided with a charge for generating a cutting flame and an activating device coupled to the charge. A method for cutting target material is also provided in which the cutting apparatus has an elongated nozzle positioned generally adjacent to a surface of a target material to be cut. The cutting apparatus may be joined with one or more housings to provide a ganged together or joined cutting apparatus. The effect of this ganged cutting apparatus is to provide an extended linear cutting action on the surface of the target material. In addition, in an opposed cutting apparatus, two housings are positioned with their nozzle channels in opposition to permit cutting target material from two directions.

The present invention relates to a CVD-coated cutting tool insert with a TiC x N y -layer with a low tensile stress level of 10-300 MPa and an ±-Al 2 O 3 -layer with a high surface smoothness of <0.1 µm as measured by AFM-technique. This is obtained by subjecting the coating to a first intensive wet blasting operation with a slurry consisting of F80 grits of Al 2 O 3 followed by a second wet blasting treatment with a slurry of F320 grits of Al 2 O 3 .

The cutting element is designed in a cube shape with its upper surface (22) and its lower surface surrounded by an elevated border. The lateral border sections, serving as the cutting edges (26, 27a, 28a, 29), are exceeded in height by the corner areas (32, 34a), which can be flattened at the outer surface. Several raised areas (42, 43, 44, 45) can be integrated in the upper surface and the lower surface of the central area (22), as well as grooves, parallel positioned along the surfaces of the border segments (26, 27a, 28a, 29).

The present invention relates to improvements in or relating to vegetation cutter apparatus. In particular, it relates to improvements in construction and manufacture of housings for lawn mowers. We describe a lawnmower having a deck with a lower surface defining a cutting chamber, a cutting element mounted within the cutting chamber, a motor assembly driving the cutter element, the motor being mounted on an upper surface of the deck, wherein the vegetation cutting apparatus further comprises a discharge chute having a discharge chute inlet in communication with the cutting chamber and a discharge chute outlet, a cover covering at least a portion of the motor assembly, and a pivotable deflector guard biased into a closed configuration against the discharge chute outlet. The discharge chute comprises a chute floor, chute sides and a chute roof. The present invention is characterised in that at least a portion of the chute roof is formed by a portion of the motor cover.

The invention concerns a device for the upkeep of a hedge (10) comprising an element adapted to move in reciprocating motion parallel above and/or beside the hedge (10). The displacement is performed repeatedly and automatically so as to prevent the hedge from growing beyond a predetermined limit by the trajectory of the mobile element. The mobile element is shaped like a gantry and moves along one or several aerial or ground rails (4). The ridges of the gantry are fitted with a cutting edge or with an abrasive element (6). The mobile element is driven by a roller (3) and is mounted on an electric gear motor (1).

A rotary anvil cutting mat comprising: na generally elongate body defining an axial length and a circumferential length, nsaid body having: nopposing first and second circumferential edges; and nopposing first a second axial edges, each arranged to have a nonlinear configuration when measured across the entirety of said axial length; na first end portion proximate said first axial edge having a first locking member, said first locking member arranged to be received between a first sidewall and a locking wedge of a channel lockup device; na second end portion proximate said second axial edge having a second locking member, wherein said cutting mat is wrappable into a generally cylindrical shape such that said first and second locking members abut in mating nrelationship, said second locking member further abuts said locking wedge opposite said first locking member, and said first and second axial edges define a seam therebetween.

The device has a transverse arm (5) that is anchored at a tibia platform that is connected to the device so that a transaction block (2) is adjusted relative to the arm`s height on a straight line guide. A joint arrangement is provided for the guide to realize different relative positions between the guide, arm and device. The arrangement has two swiveling axes that are oriented in anterior and mid lateral directions, respectively.
